Jean Charles Galissard de Marignac

Jean-Charles Galissard de Marignac (born April 24, 1817 in Geneva , † April 15, 1894 ibid) was a Swiss chemist.

In 1866 he succeeded in working out the first industrial process for the separation of tantalum and niobium on the basis of the different solubility of fluorine complexes.

In 1878 he discovered the element ytterbium while examining gadolinite more closely .

In 1880 he discovered another unknown element, which he provisionally named Y α . After the discovery by William Crookes and Paul Émile Lecoq de Boisbaudran , Lecoq de Boisbaudran named the new element on April 19, 1886 in consultation with Marignac Gadolinium with the symbol Gd.

Honors

In 1881 he was elected a foreign member of the Royal Society . In 1886 he was awarded the Davy Medal . In 1887 he was accepted as a foreign member of the Accademia Nazionale dei Lincei in Rome and was elected a member of the German Academy of Natural Scientists Leopoldina . From 1865 he was a corresponding member of the Prussian Academy of Sciences , from 1866 of the Académie des Sciences and from 1868 of the Göttingen Academy of Sciences ; he was also honored in 1889 with admission to the American Academy of Arts and Sciences .
